## Abstract

The Environmental Protection Agency (EPA) is partially approving and partially disapproving a revision to the Louisiana State Implementation Plan (SIP) submitted on December 21, 2011. This revision outlines the State's program to regulate and permit emissions of greenhouse gases (GHGs) in the Louisiana Prevention of Significant Deterioration (PSD) program. We are approving these provisions to the extent that they address the GHG permitting requirements for sources already subject to PSD for pollutants other than GHGs. We are disapproving these provisions to the extent they require PSD permitting for sources that emit only GHGs above the thresholds triggering the requirement to obtain a PSD permit since that is no longer consistent with federal law. The EPA is taking this action under section 110 and part C of the Clean Air Act (CAA or Act).
